Applications

Customer Outage Minimization—Reduce system and customer impacts with single- and three-phase tripping and reclosing. You can improve reliability by maintaining service to customers who are not on the faulted phase of the feeder.

Communications-Assisted Protection Schemes—Integrate the SEL-651R into either Ethernet- or serial-based communications networks with standard DNP3 and Modbus protocols or optional IEC 61850. You can use communications for local and remote engineering access, SCADA, real-time protection and control, loop restoration, islanding detection, blocking, and fast bus tripping schemes.

High-Impedance Fault Detection—Detect downed conductors and high-impedance faults with the optional AST. Learn more about this exciting technology.

Distributed Generation Protection—Protect both the utility and the independent power producer with one low-cost device. You can control DER interconnections with IEEE 1547-2018 protection and synchronization and innovative SEL fast islanding detection.

Inrush Detection—Detect transformer energization or motor startup, and block tripping for inrush conditions with a second-harmonic blocking element. The harmonic detection element lets you block selected tripping elements until the inrush subsides.

Load Shedding—Use underfrequency and undervoltage elements to implement basic load-shedding schemes. For more advanced load-shedding schemes, rate-of-change-of-frequency (ROCOF) elements can shed load for increasing or decreasing frequency.

Speed Up Distribution Protection—Combine the SEL-FT50 and SEL-FR12 Fault Transmitter and Receiver System with the SEL-651R for more intelligent protection. The SEL-FT50 Fault Transmitters, located on branches, laterals, and the main line, will wirelessly communicate the fault location to the SEL-651R in 6 ms. This allows both fast tripping for main-line faults as well as fuse-saving and fuse-blowing schemes on the same feeder.

Overview

Protection

Single-Phase Trip and Reclose
Control, trip, and reclose on a single phase in the event of a single-phase fault. Single-phase tripping maintains service to the customers on unaffected phases.

Reclosing Control
Apply four-shot reclosing with sequence coordination, synchronism check, and voltage check. When load levels vary from phase to phase, you can set trip levels independently for each phase.

Relay- and Recloser-Compatible Time-Overcurrent Protection
Apply 10 U.S. (IEEE) and IEC curves and 38 traditional curves, each customizable with time adder, vertical multiplier, and minimum response time functions to coordinate your feeder protection.

Phase and Ground Directional Elements
Securely trip forward or reverse faults for overcurrent protection. SEL’s Best Choice Ground Element logic selects the best ground directional element for system conditions.

Point of Common Coupling
Interconnect distributed energy resources safely and reliably with IEEE 1547-2018 protection and synchronization and innovative SEL fast islanding detection.

Six Voltage Inputs
Make better switching decisions and execute more complex Automatic Network Reconfiguration by knowing the voltage on both sides of the recloser for each phase.

Second-Harmonic Blocking
Detect transformer energization with the second-harmonic blocking elements. You can use the output of the harmonic detection elements to block selected tripping elements until the inrush conditions subside.

Frequency and Voltage Protection
Provide advanced load shedding or network decoupling with six levels of frequency elements and four rate-of-change-of-frequency elements along with under-/overvoltage protection.

Configurable Power Elements
Determine the real or reactive power flow direction and magnitude. Apply the elements at system intertie points, capacitor bank installations, and similar locations.

Built-In IEEE C37.118 Synchrophasors
Apply synchrophasors to improve island detection of distributed generation or for additional insight into what is happening on your distribution feeders.

Eight Settings Groups
Use the eight settings groups to easily configure multiple applications in one settings file and to fit operational situations.

Full-Function Clock Elements
Vary logic according to the time of year/week/day to accommodate variations in the load type for seasonal or other predictable load changes.

Communications

IEC 61850 Communications Protocol
Apply optional IEC 61850 communications for guaranteed performance of substation automation and control. You can streamline configurations of IEC 61850 enabled relays with acSELerator Architect SEL-5032 Software.

Mirrored Bits Communications Technology
Provide fast and reliable relay-to-relay communication for advanced communications-assisted protection, network reconfiguration, pilot protection, and restoration schemes.

Modbus, DNP3, and ASCII Protocols
Integrate into new or existing networks. SCADA links, local human-machine interface (HMI), and dial-in modems can access important relay data with these popular protocols.

Simple Network Time Protocol (SNTP)
Simplify wiring and installation by receiving a time signal over existing Ethernet networks. SNTP makes a good backup to more accurate IRIG-B time synchronization. The 5 ms accuracy is adequate for basic time synchronization.

Built-In Web Server
Access basic relay information on a standard Ethernet network with the built-in web server. View relay status, Sequential Events Recorder (SER) data, metering information, and settings for easy access within a local network. Web server access requires a relay password and is limited to read-only viewing of information or to secure remote firmware upgrades requiring an additional login level.

Monitoring and Metering

Fault Location
Take advantage of accurate distance-to-fault measurements using the impedance-based fault locator.

Per-Phase and Max-Phase Recloser Wear Monitor
Monitor breaker or recloser contact wear for each phase to assist in efficient maintenance planning and troubleshooting.

Metering and Power Quality (PQ) Monitoring
The control reports fundamental, power factor, rms, energy, max./min., and instantaneous/peak demand metering data. You can simplify power quality analysis using harmonic metering to the 16th harmonic as well as PQ analysis and PQ monitoring records for voltage sag, swell, and interruption (VSSI) and load profile reports.

Event Reports
View the latest 1,000 event records with the user-defined Sequential Events Recorder (SER) to aid in testing and troubleshooting relay settings, to simplify post-fault analysis, and to help improve your understanding of protection schemes. The SEL-651R can capture event oscillography data in both Compressed ASCII and COMTRADE file formats. Event reports can record up to 60 cycles with a user-defined prefault duration and triggering.

acSELerator Team SEL-5045 Software can automatically gather relay event reports on your PC and manage them with a database. You can use synchroWAVe Event 2015 Software to display oscillograms and vector diagrams to analyze event reports.

Base Model Features

Communications Ports
The SEL-651R includes three EIA-232 serial ports, one EIA-485 port, two 10/100BASE-T Ethernet ports, one USB port, and one BNC IRIG-B port.

Display and Operator Controls
Large front-panel display and programmable operator control interface pushbuttons allow easy interaction. In addition to the navigation pushbuttons, the SEL-651R includes 12 programmable pushbuttons. The pushbuttons are preprogrammed and labeled with popular recloser control switch functions, including a “Lock” function to prevent inadvertent operation. The pushbuttons can be reprogrammed and relabeled to meet your unique application requirements.

Contact Outputs
In addition to the recloser interface, the standard configuration includes two Form C contact outputs. You can use these contacts for alarms or control points.

Secondary Voltage Inputs
The SEL-651R includes six traditional 300 Vac potential transformer inputs to monitor both sides of the recloser and verify synchronization.

Current Inputs
Each phase is monitored by a 1 A current transformer input. The neutral current is monitored by a 0.2 A sensitive earth fault (SEF) current transformer input.

Enclosure
The SEL-651R is available with two standard enclosure options: a 24.5" (W) x 30" (H) x 16.6" (D) dual-door, side-mounted, painted steel enclosure and a 17" (W) x 32.5" (H) x 14" (D) single-door, rear-mounted, painted steel enclosure, both equipped with a three-point latch. These enclosures provide space to install radios, modems, switches, security gateways, and other equipment that allow you to integrate the control into your distribution automation system.
All enclosure options achieve an IP45 rating from the IEC 60529 "Degrees of protection provided by enclosures (IP Code)" standard. The painted steel versions are also tested to meet the Type 3R category from the NEMA 250 “Enclosures for Electrical Equipment (1,000 Volts Maximum)” standard, while our optional stainless steel enclosures achieve a Type 3RX rating.

Advanced 12 Vdc Battery Charging and Monitoring System
The 12 Vdc battery charger is continually monitored, and the battery health is tested daily to ensure backup power availability. AC-powered versions of the SEL-651R include a 16 Ah battery to power the control and accessories, including security devices, radios, modems, and other communications equipment in the event that ac power is lost.

GFCI Outlet
Standard 120 Vac-powered versions of the SEL-651R include a convenient GFCI-protected outlet to power laptops or other devices.

Control Cable Interface
Select control interfaces for reclosers from ABB, Eaton (Cooper), G&W, Hawker-Siddeley, Siemens, and Tavrida. See the Recloser Compatibility tab to learn more about the supported recloser models.

Enclosure
Select the painted stainless steel versions of our enclosures for superior corrosion resistance, especially in areas prone to salt or other corrosive chemicals.

Low-Energy Analog (LEA) Voltage Inputs
Reduce costs and save space with LEA voltage inputs. You can use LEA inputs for three or all six voltage input channels. The SEL-651R supports many popular reclosers that have sensors built right into the recloser bushings (eliminating the need to hang and wire potential transformers to measure the line voltages).

High-Impedance Fault Detection
Detect more high-impedance faults than with traditional protection by using AST.

Additional Inputs and Outputs
Add seven inputs and eight outputs. Options include: seven 12 V inputs with five Form A outputs and two Form C outputs, or two 125 V inputs and five 12 V inputs with five Form A outputs and two Form C outputs.
